Abstract: A probe has a substantially bar shape, and includes a tip end, a base end, and a body portion that is located between the tip end and the base end and has a thickness in a thickness direction orthogonal to an axial direction of the substantially bar shape thinner than the tip end. The body portion includes a slope surface that is continuous with the tip end and is inclined with respect to the axial direction in a direction in which the thickness becomes gradually thinner with increasing distance from the tip end. A first region having a surface shape that bulges outward is provided in at least a part of the slope surface.

Abstract: A rotor to be used in combination with a wheel speed sensor forming part of an anti-lock brake system. The rotor comprises an annular axial central section formed of a magnetic material. First and second annular axial end sections are coaxial and integral with the central section. The first and second annular axial end sections are formed of the magnetic material and arranged such that the annular axial central section is located between the first and second annular axial end sections. A plurality of holes are formed in the annular axial central section. The holes are arranged at equal intervals in the peripheral direction of the annular axial central section. A plurality of first and second depressions are respectively formed in the first and second axial end sections. A pair of the first and each second depressions are respectively located opposite to each other and connected with each hole.

Abstract: A rotor for an ABS wheel speed sensor which is capable of improving the yield of a material and a work effectiveness at assembly. The rotor 1 includes a ring-like rotor body 3 having a number of holes 2 arranged successively at an equal pitch, and an inner ring 4 having a C-shaped cross section and having, at at least one of its axial end portions, a flange section 6 bent and protruding outwardly. The inner ring is fitted in the interior of the rotor body 3. For coupling the inner ring 4 into the rotor body 3, the inner ring 4 is elastically deformed in diameter-reducing directions. In addition, the inner circumferential surface of the inner ring 4 is fitted onto a mating rotary shaft from the flange section side under pressure.
